Frequently Asked Questions About Calculate Letter Sum
What is the letter sum formula?
Each letter A-Z is assigned a value from 1 to 26 (A=1, B=2, ..., Z=26). Uppercase and lowercase letters both use the same mapping (a=1, A=1). The total sum is all letter values added together.
What about accented letters?
Accented letters like é or ü are counted as their base letter (e or u). Non-letter characters are ignored by default.
